2014-1-13  The disastrous impact of mining on West Virginia’s water resources goes back generations and could soon render much of the state’s water undrinkable, activists and experts say. About 300,000 people in nine counties have been unable to use their water other than to flush toilets for five days due to a chemical spill in the Elk River.

Coal Mining and Pollution

Coal Mining and Pollution Coal is recovered from the ground either by underground or surface mining. Underground mining creates voids over many square miles. Two basically different methods are used: longwall and room-and-pillar mining. Contaminated water (e.g., water containing suspended fine solids and/or dissolved minerals) may run off

Water Pollution Citizens Against Longwall Mining

Coal slurry is the mixture of coal refuse, chemicals and water generated at the processing plant when coal is separated from rock. Coal slurry is laden with metals and salts, and it is usually stored on site in massive slurry impoundments. Often coal ash is incorporated into these refuse disposal areas.
